For the backend storage, it depends what's your budget ... :o)
A minimal setup is to use nfs on a central server to host/share the same
data across all your machines ... the problem in this config is that the
nfs server becomes the single point of failure ... so why not using a
simple heartbeat solution for 2 nfs servers acting as one and uses drdb
between these 2 nodes for the replication ...
Other method is to have a dedicate san with hba in each webservers but
that's another budget ... :o)
Just my two cents ...
